It wasn’t long after Chip Kelly made the leap from the University of Oregon to the NFL that people shifted their focus toward wondering how well Kelly and his wide-open offense are going to fare at the next level.

Former Oregon and current San Francisco 49ers running back LaMichael James said he expects a seamless transition with Kelly taking over for the fired Andy Reid with the Philadelphia Eagles.

“It’s going to go good,” James said Wednesday amid preparation for the 49ers’ NFC championship game against the Atlanta Falcons. “Anytime you have a good quarterback and a mastermind as a coach like him, you can do numerous things. He’s always going to know the defensive weakness.”

The Eagles lured Kelly away from Oregon after a drawn-out process that included numerous other candidates being interviewed.

Ultimately, Kelly might have been swayed by the Eagles because of all their playmakers: running backs LeSean McCoy and Bryce Brown and wide receivers DeSean Jackson, Jeremy Maclin and Jason Avant, among others.

“Most definitely,” James said. “It’s a perfect fit for him. He’s got all those athletes over there. LeSean McCoy, Vick, he has a lot of them. With his style of play, the Eagles are a perfect fit for him.”

There are those skeptical of Kelly’s offensive approach working well in the NFL, where the talent level isn’t always as far apart as it tends to be in college.

James said he’s “100 percent” certain that Kelly’s offense is going to flourish at the next level.

“I don’t think anybody can stop that offense,” James said. “NFL, college, high school, no matter what it is. Washington (Redskins) runs a similar offense. They do their things, too. It would be kind of similar to that. A little faster, though.”

It stands to reason that, sooner or later, NFL defensive coordinators are going to devise ways to slow down Kelly’s attack.

If so, James said, Kelly will be ready to counter with even more wrinkles, disguises and ways to maintain an edge.

“He’s going to find that weakness, no matter what it is,” James said. “He’s a smart coach. He’s brilliant. I’ve been around NFL coaches during the Combine time and now, and I rank him up there with the best of them.”
